This state corresponds toFIG. 8B . In this case, thesecond holder 44 b is not yet received in thesecond receiving hole 53. This is referred to as a first state. -
FIG. 7B is a view illustrating a state in which thefirst holder 44 a is fitted into the first receivinghole 52. This state corresponds toFIG. 8C , and is referred to as a second state. Through movement of theelement receiving unit 40, thefirst holder 44 a is moved to thesecond circle 52 b of the first receivinghole 52 and is thereby fitted into the first receivinghole 52. Simultaneously, thesecond holder 44 b may be received in thefirst circle 53 a of thesecond receiving hole 53. -
FIG. 7C is a view illustrating a state in which thesecond holder 44 b is fitted into thesecond receiving hole 53. This state corresponds toFIG. 8D and is referred to as a third state. As theelement receiving unit 40 is pivotally rotated toward a wall surface of thecabinet 10 from the state shown inFIG. 7B , thesecond holder 44 b is located in thesecond circle 53 b of thesecond receiving hole 53 and thereby is fitted into thesecond receiving hole 53. In addition, theseparation prevention bump 44 c may be inserted into thefirst circle 53 a of thesecond receiving hole 53. - When attempting to separate the
element receiving unit 40 from thecabinet 10, the user may first separate theseparation prevention bump 44 c from thefirst circle 53 a of thesecond receiving hole 53 by lifting thefirst protrusion 43 a, and thereafter separate theelement receiving unit 40 from thecabinet 10, for example, in a reverse order from the order described inFIGS. 7A-7C . - In this case, since the
element receiving unit 40 is coupled to thecabinet 10 via thefirst holder 44 a and thesecond holder 44 b, thefastening member 60 may not be necessary, however, it is available depending on embodiments. Although four fastening members have conventionally been used, only onefastening member 60 may be used and use of thefastening member 60 may not even be necessary, according to an example embodiment of the present disclosure. In addition, coupling of theelement fixing unit 40 may be possible so long as thecabinet 10 is provided with the receiving holes 52, 53 at positions corresponding to theholders element fixing unit 40.
